A maximum fluorescence can be obtained with maximum excitation by increasing a difference (Stokes shift) between an excitation peak value (absorption maximum wavelength) and a fluorescence peak value (fluorescence maximum wavelength). To provide a red or orange fluorescent protein. [MEANS FOR SOLVING PROBLEMS] A novel fluorescent protein monomerized by introducing a mutation into a fluorescent protein derived from Funia sp. Novel chromoprotein and fluorescent protein derived from common coral (Montipora. Sp), and use thereof. A protein having an amino acid sequence in which one to several amino acids are deleted, substituted, and / or added in a specific sequence, having fluorescence characteristics, and having a Stokes shift of 100 nm or more.
